[Boost.Build v2] vc 8.0 manifest problem
by Jaroslav Gresula 12 Jan '06

12 Jan '06

Running bjam.exe on the Jamroot listed below gives bin\msvc-8.0\debug\runtime-link-static\shared.dll.manifest : general error c1010070: Failed to load and parse the manifest. The system cannot find the file specified. <Jamroot> using msvc : 8.0 ; lib shared : file.cxx : <link>shared <runtime-link>static ; </Jamroot> I've noticed that removing <runtime-link>static or replacing it with <runtime-link>shared 'fixes' the problem. I use Boost.Build from the Boost CVS and MSVC 8.0 Professional Edition. -- Jarda

boost::gregorian::months : access value / serialize
by Oliver.Kowalke＠infineon.com 12 Jan '06

12 Jan '06

Hallo, I've to serialize the value of months into a databse. This requires to access the value (amount of months) stored inside of boost::gregorian::months. How can I access the internal value (nothing found in the docu)? If this is not possible which boost::date_time type should I in order to store a datetime duration consisting of the pair years and months (Oracle database type INTERVAL YEAR TO MONTH)? Regards, Oliver

I then used "-sGXX=m68k-elf-g++ -sGCC=m68k-elf-gcc -sAR=m68k-elf-ar" on my build command line. Additionally, I added support for selecting the CPU model (architecture/instruction-set) by adding the following: (I don't know how/why this works, just imitated the respective block for other architectures). Perhaps, boost build system should support (kind of) multilib builds for cross compilation, in a similar way that gcc/g++ does when cross-compiling it for targets where this applies? This enabled me to add "-sBUILD=debug release <runtime-link>static <optimization>size <architecture>m68k <instruction-set>5200" to the build command line for a Coldfire cross-build. It even somehow worked, as gcc got called with the correct -m option... # Coldfire and other m68k (WS, Tue Dec 20 16:46:10 2005). .ARCH = <architecture>m68k <architecture>native ; flags gcc CFLAGS <architecture>m68k/<instruction-set>default : -m5200 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68000 : -m68000 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5200 : -m5200 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5206e : -m5206e ; flags gcc CFLAGS <architecture>m68k/<instruction-set>528x : -m528x ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5307 : -m5307 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>5407 : -m5407 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>cpu32 : -mcpu32 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68040 : -m68040 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>68060 : -m68060 ; flags gcc CFLAGS <architecture>m68k/<instruction-set>soft-float : -msoft-float ; >So I've done a small patch to tools/build/v1/gcc-tools.jam adding >GCC_PREFIX variable, that if set up, will prefix names of all tools with >that prefix. > >So I can compile boost with > >bjam -sTOOLS=gcc -sGCC_PREFIX=arm-linux- stage > > Ah, your approach with using GCC_PREFIX is even better!

How to create a smart pointer for a non-growable, size determined by run-time array
by yinglcs2＠yahoo.com 12 Jan '06

12 Jan '06

Hi, I have a non-growable, size determined by run-time array. For example convert this from Java to C: int[] func(int size) [ int[] array = new int[size]; return array; } I was told the only way I can do that is using STL vector. But if I need to have a smart pointer for this STL vector, should I use the c++ auto_ptr? or the Boost's shared_ptr with STL vector or Boost's shared_array? Thank you. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

callback and boost:function
by Lars Schouw 12 Jan '06

12 Jan '06

Guys, First thank you for a wonderful library and all the hours of work that is put into boost to make it what it is today. Is there anyway in C++ to setup a callback to a member function that takes two arguments I am trying to use boost::function but that only works with std::bind1st that does only take one parameter. I want to wrap some existing C code with C++. The function I want to call back is declareed like this: struct X { double foo(double x , void * p); }; Idealy I would like to use lambda to remove the void* and replace it with _1, _2 etc. But I am not sure how that works with callbacks. I had a look at the libsigc++ that seems to be able to handle callbacks with more arguments but the lambda stuff does not work under Visual Studio 2003 at least.

[bjam] Inconsistency in header/library linkages
by Peter Whaite 11 Jan '06

11 Jan '06

One thing that catches me out every now and then is that I compile with the wrong boost header files. What I'd like to be able to do is omit the version number from the Makefile and include/ld the most recent `bjam install`. By default bjam hard links the libraries, e.g. libboost_serialization_gcc.a->libboost-serialization-gcc-1_33.a but there is no such linkage for the headers, e.g. /usr/local/include/boost->/usr/local/include/boost-1_33. I can maintain it by hand, but inevitably I end up forgetting. Is there something I can do to get bjam to update the header link automatically?

[lambda] Operators
by David Greene 11 Jan '06

11 Jan '06

Hi again, As can can probably guess, I'm just learning how to use the BLL. Here's another testcase I'm having trouble with: #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> #include <boost/iterator/counting_iterator.hpp> #include <vector> #include <algorithm> #include <cassert> class Test { private: int value; public: Test(int v) : value(v) {}; int get(void) const { return(value); }; }; std::vector<Test> seq; std::vector<Test>::iterator find_value(const Test &value) { using boost::lambda::bind; using boost::lambda::_1; return(std::find(seq.begin(), seq.end(), bind(&Test::get, _1) == value.get())); } int main(void) { std::copy(boost::counting_iterator<int>(0), boost::counting_iterator<int>(10), std::back_inserter(seq)); std::vector<Test>::iterator i = find_value(0); assert(i == seq.begin()); i = find_value(5); assert(i != seq.end()); i = find_value(11); assert(i == seq.end()); return(0); } [compile log below] Another question: when using bind to delay application of the member function to the object, is the object passed by reference or value on invocation? If by value, is there a way to pass it by reference? It's not relevant to this test but will be in the code I'm working on. I'm thinking of cases where I might want to run transform algorithms on Test objects. Thanks for your help.

Boost and Sun Studio 11
by Dipak Bapatla 11 Jan '06

11 Jan '06

Hi, Has anyone built Boost using Sun Studio 11 on Solaris 8? I tried to build with the boost source 1.33.1 and it was complaining about assertions ../link.cc or something like that. Then I saw a post which talked about BOOST_NO_INCLASS_MEMBER_INITIALIZATION. So I changed the file boost/config/compiler/sunpro_cc.hpp as follows //# if (__SUNPRO_CC < 0x570) # define BOOST_NO_TEMPLATE_TEMPLATES // see http://lists.boost.org/MailArchives/boost/msg47184.php // and http://lists.boost.org/MailArchives/boost/msg47220.php # define BOOST_NO_INCLASS_MEMBER_INITIALIZATION # define BOOST_NO_SFINAE # define BOOST_NO_ARRAY_TYPE_SPECIALIZATIONS # define BOOST_NO_IS_ABSTRACT //# endif I commented out the code where it was checking for compiler version less than 5.7. I was able to compile the code (atleast the ones I needed - date_time and serialization). Now when I try to use the built libraries with my test code, I get the following errors related to has_facet and use_facet. "/opt/idev3/dbapatla/NativeSTL/boostlibs/include/boost-1_33_1/boost/date_time/gregorian/gregorian_io.hpp", line 45: Error: Could not find a match for std::has_facet<std::Facet>(std::locale) needed in boost::gregorian::operator<<<char, std::char_traits<char>>(std::ostream &, const boost::gregorian::date&).
